Eboya Houga Shinryou Dragon God Large Fountain Pen
The Eboya Houga Shinryou Dragon God Large Fountain Pen combines an imposing cigar-shaped silhouette with the depth of beige, brown and almost black marbled ebonite. Its 150 mm closed length, 18 mm body and 14K gold nib give it a substantial presence in the hand. It is ideal for writers who prefer large, clipless fountain pens with warm materials and an individual pattern.
Concept and Design
The name Houga (萌芽) means “sprout”, “germination” or “something beginning to emerge”. Eboya chose this name with the wish that its fountain pens would encourage the birth of new ideas. The concept is expressed through a classic cigar or torpedo shape, with softly rounded ends and continuous lines that reflect Japanese minimalism.
The Shinryou (神龍) finish, whose name can be translated as “Dragon God” or “Divine Dragon”, refers to Shenlong, the spiritual dragon in Chinese mythology associated with clouds, storms and the rain on which agriculture depends. In Japanese, these characters are read as Shinryū, while Shinryou is the spelling used here to maintain consistency across the collection.
Eboya officially classifies Shinryou as a beige mixture, although the finished pen has a much deeper appearance. Toasted beige, brown and subtle copper-toned streaks emerge across almost black areas, recalling damp earth, polished stone or the scales of the legendary creature that inspired its name.
The distribution of these colors varies in every ebonite rod, ensuring that no two fountain pens look exactly alike. The body is made from the original colored ebonite developed by Nikko Ebonite Manufacturing and carefully polished in Tokyo to reveal its natural luster. The discreet Eboya Made in Tokyo engraving confirms the origin of the pen.
The Large Size
The Houga Large measures 150 mm when closed and has an 18 mm diameter across both the barrel and cap. These proportions give it a more substantial presence than the Medium version and provide a broad, stable grip. It is particularly suitable for larger hands or for writers who enjoy generously sized fountain pens with bold proportions.
Despite its dimensions, ebonite avoids the cold feel associated with some other materials and provides a warm, pleasant surface. The design deliberately omits a clip to preserve the continuity of the torpedo-shaped profile and maintain a clean appearance from every angle.
Functionality and Filling System
The Eboya Houga Shinryou Dragon God Large is fitted with a carefully tuned 14K gold nib designed to provide smooth, precise and controlled writing. Its broad section and generous body support a relaxed grip for writers who prefer a substantial writing instrument.
The filling system accepts both international standard cartridges and converters, compatible with brands such as Pelikan and Rotring (not compatible with Montblanc, Waterman or Caran d’Ache). Each body is individually hand-turned and polished in Tokyo. The careful assembly of its components, together with the color of the ebonite, results in a writing instrument of remarkable beauty and quality.

Care and Maintenance
To preserve the color and natural luster of the ebonite, avoid prolonged exposure to direct sunlight, heat and humidity. Store the pen in a dark place and occasionally wipe its surface with a soft cloth. If it will not be used for an extended period, remove the ink and flush the filling system thoroughly with water.
Before changing ink color or switching to an ink from another manufacturer, clean the section and feed thoroughly. Eboya specifically advises against using pigment inks in its fountain pens.

Brand History and Philosophy
Eboya is the writing instrument brand of Nikko Ebonite Manufacturing, a Tokyo company founded in 1952 and recognized as Japan’s only remaining ebonite manufacturer. Ebonite is produced by combining and vulcanizing natural rubber with sulfur, creating a durable material with a warm feel and a distinctive luster developed through careful polishing.
In 2008, Nikko Ebonite succeeded in developing its own colored and marbled ebonite varieties. One year later, it opened the Eboya shop and began selling its original fountain pens. The Houga expresses this combination of technical knowledge and Japanese design sensitivity through a refined shape that makes every variation in the material an essential part of the finished pen.
“Like a sprout growing beneath the strength of the dragon, the Houga Large gives every new idea a bold and confident presence.”
